Theoretical Study of Structures and Ring-Puckering Potential Energy Functions of Bicylo[3.1.0]hexane and Related Molecules.

Ab initio computations using the MP2/cc-pVTZ method have been carried out to calculate the structures and relative energies of the different conformations of five bicyclic molecules including bicyclo[3.1.0]hexane, 3-oxabicyclo[3.
